Assessment of biosimilarity under the BPCI Act

Biosimilars/Research | Posted 08/02/2013

The Biologics Price Competition and Innovation (BPCI) Act defines a biosimilar as a product that is highly similar to the reference product notwithstanding minor differences in clinically inactive components and without clinically meaningful differences in terms of safety, purity, and potency. Although draft guidances issued by FDA do begin to clarify the issue, little or no discussion regarding how similar is considered highly similar is given in the BPCI Act and no criteria for assessing biosimilarity were mentioned [1].

G-CSF biosimilars – World Marrow Donor Association position

Biosimilars/Research | Posted 08/02/2013

The World Marrow Donor Association (WMDA) has expressed its position on the use of granulocyte colony-stimulating factor (G-CSF) biosimilars in healthy donors in an article published in the journal Haematologica [1].

Mobilization of stem cells in healthy donors by G-CSF biosimilars shows comparable efficacy and safety to Neupogen

Biosimilars/Research | Posted 01/02/2013

Originator human recombinant granulocyte colony-stimulating factor (G-CSF) filgrastim has been widely used for the mobilization of CD34⁺ stem cells in healthy donors. However, there is limited experience with the use of biosimilar G-CSF for the mobilization of peripheral blood stem cells (PBSCs), especially in healthy donors. A recent study by Professor Schmitt and co-authors has addressed this issue and found that biosimilar G-CSF showed comparable efficacy and safety with reference G-CSF (Neupogen) when used for the mobilization of CD34⁺ stem cells, as well as CD3⁺ T-cells and nucleated cells, in healthy donors [1].

A life-threatening complication for patients undergoing chemotherapy is febrile neutropenia, involving a loss of neutrophils (white blood cells) and fever [1]. Granulocyte colony-stimulating factors (G-CSFs) are growth factors, which stimulate the bone marrow to produce white blood cells and restore neutrophil production. In oncology and haematology, G-CSF is used with certain cancer patients to accelerate recovery from neutropenia after chemotherapy, allowing higher-intensity treatment regimens.

Biosimilarity and interchangeability under the BPCI Act

Biosimilars/Research | Posted 24/01/2013

In the US, the Biologics Price Competition and Innovation (BPCI) Act was signed into law on 23 March 2010, giving FDA the authority to approve biosimilars. FDA then issued guidelines for biosimilar applications in February 2012 in the form of three draft guidance documents [1]. Despite this, there remain scientific issues regarding the assessment biosimilars and the criteria for establishing biosimilarity and interchangeability of biosimilars [2].

Overview of research on analytical techniques in the manufacturing of biosimilars in 2012

Biosimilars/Research | Posted 18/01/2013

Period: January to August 2012

Biologicals are large, complex and heterogeneous proteins with variable molecular weights, typically ranging from 18,000 to 45,000 Da. The active substance of a biological is a collection of large protein isoforms and not a single molecular entity. This fact makes manufacturing of biosimilars much more of a challenge than when producing traditional small molecule generics. It also makes it highly unlikely that the active substances between two products are identical and makes it extremely difficult to establish biopharmaceutical equivalence using analytical techniques.

Teva asks FDA to delay approval of Biogen’s MS drug

Biosimilar monoclonal antibodies on the horizon in Europe

Biosimilars/Research | Posted 11/01/2013

European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use adopted the final guideline on biosimilar monoclonal antibody (mAb) and it came into effect in December 2012. The agency is also currently reviewing two marketing authorization applications (MAAs) for the biosimilar mAb infliximab.

Significance of locally produced biosimilars in Iran

Biosimilars/Research | Posted 11/01/2013

Biopharmaceuticals, drugs produced by live cell culture, have a fast growing market for the treatment of a range of conditions. Despite their clinical importance, however, their cost could impose an increasing burden on either national healthcare systems or patients’ out-of-pocket expenses. The potential for reducing the costs of biopharmaceuticals is therefore attracting the attention of policymakers in the health sector.

Biosimilars applications under review by EMA – 2012 Q4

Biosimilars/General | Posted 11/01/2013

Last update: 23 August 2013

European Medicines Agency (EMA) is the body responsible for approval of biosimilars within the EU. A legal framework for approving biosimilars was established in 2003. Approval of biosimilars is based on an abbreviated registration process, which allows biosimilars manufacturers to provide a reduced package of information compared to originator drugs, provided they can prove ‘similarity’ to the originator or ‘reference drug’.

Overview of research on manufacturing statistics and innovations of biosimilars in 2012

Biosimilars/Research | Posted 14/12/2012

Period: January to August 2012

Manufacturing of biosimilars is much more challenging than producing traditional small molecule generics. Reasons for this include, in the first place, the huge costs associated with manufacturing of biosimilars, along with the fact that the risk of failure for biosimilars is significantly higher than that for small molecule generics. Secondly, biosimilars are larger and more complex molecules to manufacture. Finally, minor changes in the manufacturing process can cause significant changes in efficacy or immunogenicity.

Comparison of EPARs for G-CSF biosimilars approved in Europe

Biosimilars/Research | Posted 14/12/2012

All biosimilar G-CSFs were approved using Amgen’s Neupogen as the reference product. Filgrastim ratiopharm was withdrawn on 20 April 2011.
